1. Get the right foundation

In terms of colour matching your foundation, you'll need to consider that most people have either a yellow or pink undertone. So do foundations. When you get it wrong, your colour will look 'off' and skin a bit dull.

2. Keep an eye on white spots on your nails

White spots on your nails rarely indicate a nutritional deficiency, and as for 'milk spots', that's an old wives' tale. White spots on your nails, or leukonychia as the pros like to call it, is normally the result of 'mild trauma'. In other words, it's a form of light bruising that no amount of extra calcium will fix. If you do have bigger streaks on every nail however, get it checked by GP.

3. Always file your nails in one direction

When you file your natural nails, don't move you nail file in a back-and-forth motion. It'll lead to split fibres, leaving you with weaker, damaged or flaky nails. Always file smoothly from one side to the other, then go back and pull again in the same direction.

7. Exfoliate to keep your pores clean

Pores don't have muscles so they can't actually perform the contraction that would let them open and close literally. It's true that steaming your face can help loosen underlying grime, making blackheads and dirt easier to remove, but when it comes to a deep clean? Use exfoliator and a gentle scrubbing action.

9. Colour correctors rule

When using camouflage makeup always consider the colour of what you're trying to hide. Dark circles, for example, contain shades of blue, so you need an orange/apricot corrector. Green creams will neutralise any redness, yellows will cancel out purple shades like bruises or some especially dark circles, meanwhile lavender shades can help lift sallow complexions and dull olive skin.
